spae-check

spae-check is a skill for Claude Code from mystilleef/spae-framework. It costs 37 tokens per session (1,986 once invoked), scanned C, original, MIT.

A verification checkpoint in the SPAE workflow that compares the current implementation with the task’s planned intent, acceptance conditions, and verification steps.

In plain words
What is it for?
It is for checking source files, tests, and logs, then routing the task to fixing, rebuilding, or final verification.
Why use it?
It reveals whether the task is complete or identifies gaps that need fixing before the workflow continues.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

spae-check scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Check (SPAE)

When to use

  • STATE.json reports phase: check.
  • Cursor names active task.

Goal

  • Compare active task implementation against PLAN.md Intent, Acceptance, and Verification.
  • Route gaps to /fix or advance clear task.

Input

Read:

  • .spae/current/STATE.json (consult references/STATE.md for field reference, directives, and phase snapshots)
  • Active task section from .spae/current/PLAN.md (Intent, Acceptance, Verification)
  • Source files and test logs scoped to active task

Workflow

  1. GATE—Read .spae/current/STATE.json; confirm phase: check and active_task_id. Self-heal state drift: if tasks[active_task_id] reads "todo", correct it to "in_progress" and write STATE.json before proceeding. Halt on state drift: if tasks[active_task_id] reads "done", halt. Read active PLAN.md task section; confirm title, Intent, Acceptance, Verification. Halt on missing or malformed input; report and make no changes.
  2. ORIENT—Verify active task; hand off to /fix, /build, or /verify. Leave source, tests, config, docs, PLAN.md, SPEC.md, task scope, and workstream completion untouched.
  3. PLAN—List active-task Acceptance outcomes and Verification steps. Map evidence for declared Intent; scope source/test reads to active task. Never read SPEC.md.
  4. ACT—Execute:
    • Run active-task verification steps and project checks. Without automation, inspect source, logs, or scripted probes for observable behavior.
    • Confirm every Acceptance outcome and Intent against evidence.
    • Label findings with exactly two tags:
      • Gap: unmet Acceptance, failed Verification, Intent mismatch, speculative abstraction, unrequested complexity, defensive bloat beyond task Scope, or a self-introduced cleanup violation per references/cleanup-guide.md. Include unmet item, file:line, expected vs actual, reproducible evidence. Blocks a clear result.
      • Observation: minor concern outside task scope, unrequested edge-case coverage, theoretical risk. Report only; never write to FIX.md or affect the verdict.
    • Draft gaps per references/FIX.md schema; consult references/prose-protocol.md.
  5. VERIFY—Reconcile every Acceptance, Verification, and Intent against evidence. Clear verdict only with zero gaps. Confirm drafted FIX.md matches references/FIX.md structure.
  6. PERSIST—Apply one verdict:
    • Gap found: create/overwrite .spae/current/FIX.md per references/FIX.md. Write STATE.json: phase: fix; preserve status, cursor, task registry, version, workstream. Active task stays in_progress.
    • Task clear, tasks remain: write STATE.json: mark active task done, advance cursor to next "todo" task, phase: build.
    • Final task clear: write STATE.json: mark active task done, retain cursor active task ID, phase: verify.
    • All branches: re-read STATE.json after writing; on a field mismatch, rewrite and re-read before REPORT.
  7. REPORT—Emit result per directives. Template B after gap, D after clear nonfinal task, E after clear final task. Observations under Findings only.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
